A pre-existing condition is anything symptomatic, diagnosed, or noted in the record before the waiting period ends — usually a 6–12 month lookback. For Rottweilers, the common exclusions come from puppy-visit notes about hip laxity, intermittent lameness, or GI sensitivity. Curable conditions may re-cover after 6–12 symptom-free months.
Pre-existing conditions are the #1 reason pet insurance claims get denied. For Rottweilers, this is the rule that determines whether hip dysplasia and elbow dysplasia are insurable at all. For Rottweilers, the rules are stricter than most owners expect — and the things that trigger an exclusion often look harmless in vet records.
A pre-existing condition is any condition that showed signs, symptoms, or a diagnosis before your policy's effective date — including the waiting period. Insurers don't need a confirmed diagnosis. A note in your vet records saying "mild intermittent right forelimb lameness, will monitor" is enough to permanently exclude elbow and shoulder issues.
Most insurers review the past 12 to 24 months of vet records when you submit a claim. A few (Embrace, ASPCA) have curable-condition rules: if a condition resolves and shows no symptoms for 12 months, they'll start covering it again. Most others (Trupanion, Healthy Paws) treat any documented history as permanently excluded.
If your Rottweiler is young and healthy, enroll now. Compare the best pet insurance plans for Rottweilers and lock in coverage before any new vet record is created. The fewer vet visits in the past 24 months, the cleaner your record looks. If you have an older Rottweiler with some history, get quotes anyway — different carriers handle ambiguous notes differently. Embrace and ASPCA are generally the most flexible on pre-existing rulings; Healthy Paws and Trupanion are the strictest.
Specific to Rottweilers and other large breeds: many insurers apply bilateral exclusions. If your dog tears the right ACL before enrollment, the left ACL is automatically excluded too — even though it's a different leg, it's considered the "same condition." The same logic applies to elbow dysplasia and hip dysplasia. Trupanion and Embrace are the carriers most likely to cover the contralateral side; Healthy Paws explicitly does not.

Any condition that showed signs, symptoms, or a diagnosis before your policy's effective date — including the waiting period. A vet note like 'mild intermittent lameness, will monitor' is enough to permanently exclude joint coverage.
Most insurers review the past 12 to 24 months of vet records. A few (Embrace, ASPCA) will re-cover certain curable conditions if symptom-free for 12 months; Trupanion and Healthy Paws treat documented history as permanently excluded.
You can, but the new policy will treat any diagnosed condition as pre-existing — even if your old policy was already paying claims for it. Switching after a major diagnosis usually loses coverage for that condition.
